Yes @Titus I already tried that one! It's really cool, because PVA is translucent and you can see a shape inside, but you can't guess what it is. I gave it to a friend as a birthday present and it saved me some money of a real present.

If I print some more I will take some pictures while printing, it's really addictive to watch the model being printed inside another shape.

Not entirely sure how to make sure Cura uses the PVA as 'egg' material, but then again I've never done dual extrusion

I should start printing again. @SandervG I haven't seen a contest for a while now Not expecting a win an UM3, perhaps nothing physically even(see suggestion topic on how to proceed with contests). Just want to get kickstarted to print something

Well it's quite easy to do (assuming you have the model you want to print and the egg designed).

Load the model you want to print in Cura assign the first core to it (PLA)

Load the egg model assign the second core to it (PVA)

Merge the models in Cura

Print

Voila

I think the tricky part (maybe not) is to design the egg because you need to make sure it surrounds the model perfectly (ideally also creating a platform for the model's first layer to be printed on

I will try to share soon some Pokemon eggs designs so you can try it by yourselves. The design process is just as Didier said. I designed the egg surrounding the model and I exported it as if it was a PLA/PLA print, but I chose to use PVA for the outer part (the egg), with a nice surface to start printing PLA just over it without any adhesion problem.

You are totally right! There is a contest coming up pretty soon, I'll let you know when it is live.

I wanted to create a more long-term concept for the contests, but I kinda got overwhelmed with the Ultimaker 3 launch.

When the dust has settled down a bit I will collect my different thoughts and share them. In the meantime, if you have any thoughts, this topic is still open

Those are bloody fantastic. I could nit pick about things that doesn't quite fit my ideal for those particular monsters, but damn, who cares. Those sculpts, prints and most importantly, paint jobs, are amazing.

Our picks

We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
